Improved mode of transmitting motion



@we am,

Letters Patent No. 96,615, dated November 9, 1869.

IMPROVED 'MODE OF TRANSMIITINC-iF MOTION.

The Schedule referred to in these Letters Patent and making part of the same.

, accompanying drawing, forming part of this specification.

This invention relates to a new and improved method of transmitting motiomfrom one revolving shaft to another, `whereby belts and gear-wheels are dispensedwith, and consists in the arrangements hereinafter described.

In the accompanying drawing- Figure l represents a front View, and

Figure 2, a side view of the arrangement.

A and B are two shafts, supported by the vertical standards O.

l) is a face-wheel on tbe shaft A, and

E is a face-wheel on the shaft B.

These two face-wheels are connected by the rod F. At A, the rod is attached to a Wrist-pin in the face of the wheel. `Atfthe other end, it is attached to a wrist-pin in a link, G, which link is attached to the face of the wheel E.

The lower end of the rod F'does not describe a perfcct circle, and thelink G compensates for the variation from a true circle.

H is a grooved plate, face-don the standard O', on a line with the shafts A and B.

The connecting-rod F is pivoted to a block, I, which slides in a groove in the plate H as the rod is carried up and down by the iice=wheels.

The pivot J, which connects the rod to the block I, forms a central swivel-joint, on which the rod oscillates.

Thev dri ving-power may be applied to either shaft. The shafts will revolve in opposite directions, while the motion will be transmitted from one to the other in a positive manner, without the aid ci gearing, and, consequently, without noise.

This method of transmitting motion is admirably adapted tosewing-lnaehines, and to 'many other useful purposes. l

The above-described means for transmitting motion constitute a valuable improvement upon the patent granted to me, J uly 27 1869.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The combination of a lever, F, swivelled to a block, I, with a grooved -and 4fixed guide, H, the two disks D E, and the link G, as and for, the Vpurpose specified.
